TECHNICAL FIELD

This document relates to a complex comprising a mineral-amino acid compound and a polysaccharide, including compositions and methods of making and using such complexes.

BACKGROUND

Minerals are required as part of the human diet for good health. For example: calcium is a major component of bones and teeth; iron is an essential constituent of hemoglobin; copper, magnesium, and zinc are co-factors for a variety of enzymes; and manganese and selenium can function as antioxidants and contribute to endothelial integrity. Mineral deficiencies can lead to poor health and specific disorders. The human body requires traces of minerals, e.g., calcium, iron, copper, and zinc, in soluble form to provide metallic ions which are bioavailable within the bloodstream. With the increase in highly processed and convenience foods, however, there are concerns that the typical diet in today's conditions may not contain sufficient levels of such minerals.

Naturally occurring minerals found in foods are often chelated or bound within an organic matrix. Minerals found in dietary supplements, however, are often in the form of an inorganic salt, for example, as a mineral sulfate. These inorganic mineral species are more reactive and can catalyze production of free radicals, which have been associated with various degenerative diseases or conditions, within the digestive tract.

DETAILED DESCRIPTION

This document provides a complex comprising a mineral-amino acid compound and a polysaccharide. For example, the document provides compositions containing such complexes and methods of making and using such complexes.

A complex, as described herein, comprises a mineral-amino acid compound and a polysaccharide. In some embodiments, the mineral-amino acid compound and the polysaccharide are conjugated. In some embodiments, the conjugation includes one or more of a covalent, coordinate covalent, Van der Waals interactions, hydrophobic, hydrogen, or ionic bond.

A mineral-amino acid compound can include any mineral having a dietary benefit that is chelated or complexed (e.g., forms a salt with) an amino acid. In some cases, the mineral-amino acid compound can be an amino acid chelated mineral. In some cases, the mineral-amino acid compound can be a mineral-amino acid complex or salt. Any mineral having a dietary or health benefit can be used in the complexes described herein. For example, chromium; calcium; copper; iron; magnesium; manganese; molybdenum; potassium; zinc; selenium; and iodine.

Any amino acid that can form a chelate or complex with a mineral can be used in the complexes described herein. In some cases, the amino acid portion of a mineral-amino acid compound can be one or more natural or unnatural amino acids. For example, an amino acid can be a natural amino acid. As used herein, the term “natural” amino acid refers to one of the twenty commonly occurring amino acids. Natural amino acids can be in their D or L form. For example, a natural amino acid can be selected from the group consisting of L-alanine, L-arginine, L-asparagine, L-aspartic acid, L-cysteine, L-glutamic acid, L-glutamine, L-glycine, L-histidine, L-isoleucine, L-leucine, L-lysine, L-methionine, L-phenylalanine, L-proline, L-serine, L-threonine, L-tryptophan, L-tyrosine, L-valine, and mixtures thereof. In some cases, an amino acid is selected from L-glycine and L-aspartic acid.

A polysaccharide can be any grouping of sugars (e.g., monosaccharides) linked together. For example, a polysaccharide can include cellulose derivatives. In some cases, a polysaccharide can include polyhexoses, polypentoses, and derivatives thereof. In some cases, a polysaccharide can be selected from the group consisting of polydextrose, starch, polygalactan, polymannan, chitin, chitosan, chondroitin, polyfructose, pectin, and derivatives thereof. In some cases, a polysaccharide can be a polyfructose (e.g., inulin). In some cases, inulin can have a degree of polymerization ranging from about 2 to about 100 (e.g., about 2-10; about 12-15; about 20-30; about 25-45; about 30-40; about 50-75; about 45-65; about 50-55; about 70-80; about 75-90; and about 92-100).

A complex, as described herein, can be prepared by heating a composition comprising water, one or more mineral-amino acid compounds, and one or more polysaccharides at a temperature from about 100° F. to about 180° F. (e.g., 100° F.; 110° F.; 120° F.; 125° F.; 130° F.; 140° F.; 145° F.; 150° F.; 160° F.; 165° F.; 170° F.; 175° F.; and 180° F.). In some cases, the composition can be heated at from about 140° F. to about 180° F. In some cases, the composition can be heated at about 160° F. In some cases, the composition can be heated for from about 5 minutes to about 30 minutes (e.g., about 5 minutes; about 10 minutes; about 15 minutes; about 20 minutes; about 25 minutes; and about 30 minutes). In some cases, the composition can be heated for about 20 minutes. In some cases, the complex can be dried, for example, to a moisture content of less than about 15% (e.g., less than about 14%, less than about 12%, less than about 10%, less than about 8%, less than about 5%, and less than about 2%) following heating.

A complex can be prepared using a ratio of mineral-amino acid compound to polysaccharide ranging from 10:1 to 1:10 (e.g., 10:1; 6:1; 5:1; 4:1; 3:1; 2:1; 1:1.5; 1:1; 1:1.5; 1:2; 1:3; 1:4; 1:5; 1:6; and 1:10). For example, a ratio of mineral-amino acid compound to polysaccharide can be 5:1 or 1:1. In some cases, a mineral-amino acid polysaccharide complex can be zinc aspartate:zinc glycinate:inulin (degree of polymerization of 12-15) having a ratio of 50:30:20 by weight. In some cases, a mineral-amino acid polysaccharide complex can be iron aspartate:iron glycinate:inulin (degree of polymerization of 2-10) having a ratio of 25:25:50 by weight.

The complexes described herein can have properties that distinguish them from a simple mixture of the same mineral-amino acid compound and polysaccharide. For example, a complex of a mineral-amino acid compound and a polysaccharide can diffuse slower across a 3500 MW cutoff dialysis membrane then an uncomplexed mixture of the same mineral-amino acid compound and polysaccharide (see Example 2). The complex also can exhibit a different Fourier-Transform Near-IR (FT-NIR) spectrum compared to a similar uncomplexed mixture as determined by an industry standard correlation factor (see Example 3).

This disclosure also provides for a composition comprising two or more complexes as described herein. For example, a composition can comprise two or more of a calcium-amino acid polysaccharide complex; iron-amino acid polysaccharide complex; iodine-amino acid polysaccharide complex; magnesium-amino acid polysaccharide complex; zinc-amino acid polysaccharide complex; selenium-amino acid polysaccharide complex; copper-amino acid polysaccharide complex; manganese-amino acid polysaccharide complex; molybdenum-amino acid polysaccharide complex; and boron-amino acid polysaccharide complex. In some cases, the mineral-amino acid polysaccharide complex can include a mineral-amino acid compound comprising 75% aspartate and 25% glycinate. In some cases, the mineral-amino acid polysaccharide complex can include polyfructose. In some cases, the mineral-amino acid polysaccharide complex can include inulin having a degree of polymerization ranging from about 2 to about 100. In some cases, the mineral-amino acid polysaccharide complexes can include inulin having a degree of polymerization of about 12-15.

In some cases, the composition can also include one or more of vitamin A; vitamin C; vitamin D; vitamin E; vitamin K; thiamin; riboflavin; niacin; vitamin B6; folate; vitamin B12; biotin; pantothenic acid; and phosphorous.

In some cases, a composition can comprise:

The phrase “total daily dose” as used herein refers to the amount of active ingredient administered over a 24 hour period. For example, the amount of zinc amino acid polysaccharide complex in a total daily dose is calculated based on the amount of zinc administered over 24 hours, not on the amount of zinc amino acid polysaccharide complex administered over 24 hours. A total daily dose may be prepared and administered in the form of one or more tablets (e.g., two tablets, three tablets, four tablets, five tablets, and six tablets). In some cases, the one or more tablets can be administered in one or more dosages over the course of 24 hours (e.g., one dose, two doses, three doses, four doses, five doses, and six doses), wherein the one or more dosages do not exceed the total daily dose.

A mineral-amino acid polysaccharide complex, as described herein, can reduce the formation of free radicals in the intestinal tract as compared to an uncomplexed mineral (e.g., a mineral sulfate, chloride, citrate, or gluconate). In some instances, the mineral-amino acid polysaccharide complex can be an iron-amino acid polyfructose complex or a copper-amino acid polyfructose complex. In some instances, the mineral-amino acid polysaccharide complex can be a glycinate or aspartic acid-iron or copper species complexed with inulin. In some instances, the uncomplexed mineral can be an inorganic salt (e.g., a mineral sulfate, chloride or oxide). Reduction in the formation of free radicals can include reduction in the formation of reactive oxygen species (ROS) such as hydroxyl radical, peroxide, and superoxide radical. ROS can initiate radical chain reactions within the body. For example, an uncomplexed mineral provided in a dietary supplement can catalyze the formation of ROS that can oxidize one or more antioxidants from the dietary supplement (e.g., ascorbic acid, tocopherols, carotenoids, lipoic acid, natural plant phenols and flavonoids, and polyunsaturated fatty acids). Without being bound by theory, a complexed mineral, however, is thought to be protected by the amino acid and/or the polysaccharide and thus is less able to catalyze free radical formation. When administered in the form of a dietary supplement, a reduction in the formation of free radicals can decrease the oxidation of any antioxidants present in the dietary supplement itself.

Accordingly, further provided herein is a method for providing a mammal with a mineral and antioxidant mixture with reduced mineral-catalyzed oxidation. In some instances, the method includes administering to the mammal a composition comprising a mineral and an antioxidant, wherein the mineral is in the form of a mineral-amino acid polysaccharide complex, as described herein. The mineral-amino acid polysaccharide complex can exhibit reduced mineral-catalyzed oxidation of the antioxidant compared to an uncomplexed mineral or a mineral administered as an inorganic salt. In some instances, the reduced rate of oxidation occurs in the intestine of the mammal.

Beyond stabilization of antioxidants present in a dietary supplement, a reduction in the formation of free radicals can also reduce oxidation of bio-molecules such as lipids, proteins, and DNA. In some cases oxidative damage of bio-molecules can lead to formation of many different intermediate radicals including toxic and/or pathogenic products. These radical species can change the structure and/or function of bio-molecules and can provoke some degenerative diseases (e.g., inflammation, cancer, and arteriosclerosis)

This disclosure provides methods for reducing formation of a free radical, reducing the amount of a free radical, and decreasing antioxidant oxidation in a mammal or cell using a complex as described herein (see Examples 4-6, 20, and 21). For example, a complex can be an amino acid-iron or copper compound complexed with a polysaccharide. In some cases, the cell is an intestinal cell. In some instances, the reduced formation of free radicals, reduced amount of free radicals, and decreased antioxidant oxidation occurs in the mammal's intestine.

In some cases, the methods can be used in vitro, for example, reducing free radical formation, reducing the amount of a free radical, or decreasing antioxidant reduction, can be performed by contacting a cell with a complex as described herein. The contacting can be performed in the presence of cells, wherein, optionally, a free radical or an antioxidant is present within the cells, or alternatively may be performed in a cell free medium. Uses of such in vitro methods of reducing formation of a free radical include, but are not limited to, use in a screening assay (for example, wherein the amino acid-iron or copper compound is used as a positive control or standard compared to compounds of unknown activity or potency in reducing formation of a free radical).

In some cases, the methods can be used in vivo, for example, reducing free radical formation, reducing the amount of a free radical, or decreasing antioxidant oxidation, can be performed by contacting a cell, in vivo, with a complex as described herein. The contacting can be achieved by causing the complex (e.g., an amino acid iron or copper species complexed with a polysaccharide) to be present in a mammal in an effective amount to, for example, reduce free radical formation. This can be achieved, for example, by administering an effective amount of the complex to the mammal, or by administering a composition comprising the complex to the mammal.

Uses of such in vivo methods of reducing free radical formation and the amount of a free radical include, but are not limited to, use in methods of treating or preventing a disease or condition such as a degenerative disease (e.g., inflammation, cancer, and arteriosclerosis). In some cases, an antioxidant can be selected from ascorbic acid, tocopherols, carotenoids, lipoic acid, natural plant phenols and flavonoids, and polyunsaturated fatty acids.

A mineral-amino acid polysaccharide complex, as described herein also has increased solubility at neutral pH as compared to an uncomplexed mineral (see Example 23). In some instances, the neutral pH occurs in the intestinal tract. Without being bound by theory, such increased solubility can increase the concentration of mineral absorbed by the body following administration.

EXAMPLES Example 1 Preparation of Zinc-Amino Acid Inulin Complex

100 g of zinc aspartate and 50 g of zinc glycinate were mixed with 150 g of inulin (degree of polymerization 12-15). 60 mL of water was added. The mixture was heated up to 140° F. with stirring for 30 minutes. The mixture was then transferred onto a drying tray and was dried overnight or until the composition reached a moisture content of 8%.

Example 2 Dialysis Model

Equal weight samples of iron(II) bis-glycinate (10.1% Fe) and inulin (degree of polymerization of 12-15) were mixed with water. The mixture was shaken for 3 minutes until reagents dissolved completely. The solution was then diluted with water to a final concentration of 2 mg/mL. 5 mL of this solution was then transferred into a dialysis tube (Fisherbrand® regenerated cellulose, molecular weight cutoff=3,500) and allowed to sit for 5 minutes prior to starting dialysis. Dialysis against 100 mL of water was performed with slow agitation. Aliquots were taken every 10-15 minutes over the course of 2 hours. Iron(II) concentration was determined calorimetrically, using the reaction of 2,4,6-tri-(2-pyridyl)-s-tirazine (TPTZ) and FeSO₄ as a reference standard (see Benzie, I. F. and Strain, J. J. Anal. Biochem 1996; 239:70-6).

A sample of iron(II) bis-glycinate, processed with an equal weight of inulin (4.73% Fe) to prepare an iron(II) glycinate inulin complex was prepared (see Example 1) and dialyzed the same way.

Table 1 and FIG. 1 detail the concentration of iron(II) (μg/mL) in the dialysis solution for both samples at various time points.

TABLE 1 Dialysis time (min) Mixed Processed 0 0.0 0.0 10 5.9 1.4 20 11.1 2.6 30 19.9 7.1 45 25.0 12.7 60 39.0 25.9 90 62.7 49.0 120 75.9 63.3

A smaller amount of the iron-amino acid inulin complex penetrated through the membrane at all time points compared with the simple mixture (Table 1 and FIG. 1). These results indicated that the complex was a larger species and not formed simply upon mixture of the components.

Example 3 FT-NIR Model

Fourier Transformed (FT) Near Infrared spectrometry was performed on a Spectrum One NTS V.N3 (Perkin Elmer). A manganese aspartate inulin complex was prepared using a 1:1 weight ratio of mineral-amino acid compound to inulin (see Example 1). Dry manganese aspartate was combined with an equal weight of inulin powder, and the mixture was gently agitated to obtain a homogeneous powder that was used as a control (see FIG. 2).

The complex and mixture failed the identity test based on an industry standard calculated correlation factor. Correlation—0.886 (pass>0.95); Factor—0.679 (pass>0.95). In addition, visually, both FT-NIR spectra displayed different intensities in some areas of the spectrum. In particular, new peaks were observed in the spectrum of the complexed sample.

These results indicate that the complexed sample and the simple mixture are different chemical entities.

Example 4 Ascorbyl Radical Kinetics

Samples of iron(II) sulfate, iron(II) bis-glycinate (FeAAC), and an iron(II) bis-glycinate inulin complex (FeAAC/OF; ratio 1:10 w/w) were analyzed using EPR spectroscopy to determine their ability to generate the ascorbate radical, i.e. to catalyze ascorbic oxidation. The samples were dissolved in 10 mM HEPES buffer (pH 7.2) to a final concentration 0.9 mM of iron. Ascorbic acid was dissolved in the same buffer at a concentration of 4.04 mM.

The iron solutions were mixed with the ascorbic acid solution, and the mixture was transferred into capillary tubes for measurement. Multiple readings were performed over 30 minutes.

EPR measurements were performed in 50 μL capillary tubes at room temperature using a Bruker ER-200 X-band EPR spectrometer. Instrumental conditions included: a microwave frequency of 9.71 GHz; a center field of 3472 G; a scan range of 10 G; a scan time of 20 seconds; a modulation value of 1.25 G; a time constant of 0.5 seconds; a microwave power of 10 mW; and an instrumental gain of 2×10⁶.

The relative amplitudes of the ascorbyl radical signal, which can be correlated to the concentration of ascorbyl radical present in the solution, were measured (Table 2).

TABLE 2 Time (min) FeSO₄ FeAAC FeAAC/OF 1.5 100% 100% 100%  3.5 76% 74% — 5.5 64% 65% 80% 10.0 24% 47% 79% 14.0 14% 33% 69% 20.0 10% 19% 63% 28.0 5% 19% 61%

The ascorbyl radical was stabilized for a longer period of time when the reaction was catalyzed by iron glycinate, compared with the iron sulfate (Table 2). Moreover, the iron glycinate inulin complex increased the lifetime of the ascorbyl radical by an even greater degree.

Example 5 Hydroxyl Radical Formation

The rate of hydroxyl radical formation catalyzed by a complex comprising an iron- or copper-amino acid inulin complex was compared to the iron- or copper-amino acid compound alone.

Mineral (Cu or Fe) was dissolved in 10 mM HEPES buffer (pH 7.2) containing DMPO. Iron and copper were used in the form of amino acid compounds (i.e., glycinates; AAC) and as amino acid inulin complexes(1:9 w/w; AAC/OF). Hydrogen peroxide was added 90 seconds prior to measurement. The final composition of the reaction mixtue was metal—800 μM, DMPO—18.7 mM, and H₂O₂—61 mM.

The spin trapping reagent—5,5-dimethylpyrroline-N-oxide (DMPO) was used for monitoring hydroxyl radical. EPR conditions were: a microwave frequency of 9.71 GHz; a center field of 3472 G; a scan range of 100 G; a scan time of 100 seconds; a modulation value of 1.25 G; a time constant of 0.5 seconds; a microwave power of 10 mW; and an instrumental gain of 2×10⁶.

The relative signal amplitudes for DMPO/hydroxyl radical adduct, which can be correlated to the concentration of hydroxyl radical present in the solution, was measured (Table 3).

TABLE 3 AAC AAC/OF Fe 100% 36% Cu 100% 50%

The mineral-amino acid inulin complexes exhibited a decreased rate of hydroxyl radical formation compared to the mineral-amino acid compound alone (Table 3).

Example 6 Ability of Different Forms of Copper to Catalyze Oxidation of DCF

The rate at which various forms of copper catalyze the oxidation of DCF (2′,7′-Dichlorodihydrofluorescein) was studied using copper sulfate, a copper gluconate inulin complex (AAOC), and copper gluconate. Solutions of all copper samples were prepared in 20 mM HEPES buffer (pH 7.2) with a concentration of 25 μM. A DCF stock solution prepared in 20 mM NaOH to provide hydrolysis of acetates. The DCF stock solution was diluted in 20 mM HEPES buffer (pH 7.2) to concentration of 0.1 mM. 0.5 mL of each copper solution was mixed with 1 mL of DCF solution. The reaction was initiated by addition of 0.1 mL of 0.1% hydrogen peroxide. Oxidation of DCF was monitored by measuring its optical density at 500 nm.

The copper-amino acid inulin complex exhibited the slowest rate of DCF oxidation compared to the copper-amino acid compound and copper sulfate species (FIG. 3).

Oxidation of ascorbic acid catalyzed by copper was evaluated by monitoring oxygen consumption. Tablets were crushed to a thin powder. An aliquot of both samples, which provided an equal amount of copper, was used. Samples were incubated in 0.1N HCl for 1 hour, and then the pH was adjusted to 7.0 with sodium carbonate. Ascorbic acid was added to provide at an equal concentration in both samples. The final concentration of copper was 3.9 μM and ascorbate was 600 μM. 3 mL of each mixture was placed in a measuring cell equipped with a Clark electrode. The oxygen concentration was monitored with a BioStat Nitric Oxide System (ESA Biosciences, Chelmsford, Mass.). The oxygen consumption rate for Formula A was 319 pmol/sec, while Formula B had a consumption rate of 75 pmol/sec.

Example 19 EPR Spectroscopy of Copper Complexes

EPR spectroscopy was used to probe the nature of the aqueous copper complexes at different pH values. All EPR measurements were done in using a Bruker ER-200 X-band EPR spectrometer. Samples (50 μL) in capillary tubes (0.5 mm i.d.) were examined at room temperature. Instrumental conditions included: microwave frequency 9.71 GHz; center field 3415 G; scan rate 1000 G/100 s; modulation amplitude 2.5 G; time constant 0.5 s; microwave power 10² mW; instrument gain varied for different samples from 10³ to 3.2×10⁵. Manganese in calcium oxide was used as a reference for EPR parameters.

When either CuSO₄ or copper-amino acid (glycinate or aspartate) inulin complex (CuAAC; 5 mM) was dissolved in aqueous solution at pH 1 the EPR spectra was a single line (g=2.19; ΔH_(pp)=140 G), FIG. 4. Similar spectra were observed when these complexes were dissolved in 0.5 M perchloric acid consistent with the aquo-complex of copper. However, at near-neutral pH, the EPR of the ACC complex changed to that expected for a histidine-type complex (see Basosi R, Pogni R, Lunga G D. Coordination modes of histidine moiety in copper (II) dipeptide complexes detected by multifrequency ESR. Bull Magn Res 1992; 14:224-8). This indicates that at neutral pH, typical amino acids can become ligands to copper(II).

Example 20 Ascorbyl Radical Kinetics

Ascobyl radical kinetics were measured as described in Example 4 to determine whether the rate of copper-catalyzed ascorbate oxidation was affected by the addition of either CuSO4 or a copper-amino acid (glycinate or aspartate) inulin complex (CuAAC). As shown in FIG. 5, the introduction of copper to near-neutral solutions of ascorbate resulted in an increase in the concentration of the ascorbate radical. However, the rate of loss of this radical was significantly slowed by the CuAAC compared to the sulfate form of this metal. The loss of ascorbate radical in this system will parallel the loss of ascorbate. Thus, these results indicate that the AAC complex slows the catalytic oxidcation of ascorbate by copper.

Example 21 Copper-Mediated Oxidation of Trolox is Inhibited by CuAAC

Trolox is an analogue of vitamin E, a lipid soluble antioxidant; the phytyl tail of α-tocopherol has been replaced by a carboxyl group making Trolox water-soluble. It is a tool used to probe for antioxidant-capacity and free radical flux. The one-electron oxidation of Trolox results in the formation of a phenoxyl radical that is readily detected by EPR. All EPR measurements were done in using a Bruker ER-200 X-band EPR spectrometer. Samples (50 μL) in capillary tubes (0.5 mm i.d.) were examined at room temperature. Instrumental conditions included: microwave frequency 9.71 GHz; center field 3472 G; scan range 60 G; scan time 50 s; mod amp 1.0 G; time constant 0.5 s; microwave power 20 mW; and instrument gain 2×10⁶.

Using a Fenton system to initiate oxidations, the formation of the Trolox free radical was observed upon the introduction of copper (FIG. 6A). The concentration of the Trolox free radical was directly proportional to the amount of Cu²⁺ introduced into the system (FIG. 6B). Thus, this system appears to be excellent for determining the effectiveness of metals in initiating oxidation processes that will consume antioxidants.

When copper with different coordination environments or matrices was introduced into this system, the intensity of the EPR spectrum of Trolox radical varied with the environment. Copper sulfate produced a robust EPR signal of the Trolox free radical; when gluconate was available to coordinate the copper, the EPR signal was reduced by about 15%; however, when copper was introduced as part of an AAC complex, the EPR signal intensity was reduced by approximately 50%, compared to CuSO₄. This is consistent with the observations with ascorbate indicating that mineral-AAC reduces the oxidative flux in a system.

Example 22 Preparation of Mineral-Amino Acid Polysaccharide Complexes

A copper-amino acid polysaccharide complex was prepared by suspending Cu carbonate with glycine or aspartic acid followed by inulin at final ratio 1:4:01. After stirring for 10 min at 80° C., the mixture was dried in oven.

An iron-amino acid complex was prepared by first dissolving FeSO₄ (1 mol) in water; then NaOH was added to precipitate the iron. Glycine or aspartic acid (2 moles) was added to a suspension of the Fe-solids, and the mixture was stirred and then dried in an oven. To prepare the iron-amino acid polysaccharide complex, glycine or aspartic acid (1 mole) was suspended in water with the iron solids; then 0.01 mole of inulin was added. After heating at 80° C., the resulting mixture was dried in oven.

Example 23 Mineral Solubility

Two forms of zinc, copper, and iron were tested for solubility at conditions close to physiological. Mineral-amino acid polysaccharide complexes were compared with inorganic forms: zinc oxide, copper sulfate, and iron sulfate. Samples, in an amount equivalent to 20 tablets, were suspended in 20 mL of water. The pH was adjusted to 1-1.2 and maintained for one hour, simulating a gastric environment. After the first hour, the pH was adjusted to 7-7.2 and maintained for another hour, simulating an intestinal environment. The product was then centrifuged and the supernatant taken for analysis. Results are presented as a percent of solubilized mineral, and the elemental recovery data is shown in Table 15.
